What is Connect Four?
Connect Four (also known as Four in a Row, Four in a Line, or Connect 4) is a classic two-player strategy game where players take turns dropping colored discs into a vertical grid. The objective is simple: be the first to connect four of your discs in a row—horizontally, vertically, or diagonally.
Despite its simple rules, Connect Four offers surprising strategic depth. Players must think several moves ahead, balancing offensive plays to create winning combinations while defending against their opponent's threats.
